Asteroid 270 Anahita Transiting IC 443, The Jellyfish Nebula
This crossing took place on the morning of December 10th, 2008 as viewed from my backyard in Tucson, AZ.
I was not aware of the transit during the imaging session, but noticed the object during my post-acquisition data reduction process.
Asteroid #270 Anahita was discovered in 1887 and is a main belt asteroid.
